After a soft reset the GPS starts up normally, finds several satellites, and sends a correct position to the program that opened it. Then it locks up and the next time it is accessed by the same or a different program it will not start. Soft reset enables it again. Hard reset or reflashing with the latest Sprint update does not fix the problem.

The settings/phone/services/location setting is ON. This is a stock Sprint CDMA Diamond.

It does the same thing with each of the startups available with the HTC GPS Tool: hot, warm, cold, and clear memory. GPS data shows up in the window of the tool as it acquires the satellites. As soon as it obtains a position the data flow stops. Closing and opening the GPS has no effect. When in this state, google maps, bing and other programs try to get a position but never see any satellites. Everything else in the phone seems to work even when the GPS is locked up. After a soft reset, all these programs get one correct position before the GPS stops working. I've tried it in more than one location.

Before I buy a replacement phone, I'd like to some advice on whether this could be a fixable problem...whatever it is, it persists after reflashing the rom. Many thanks.
